A method of producing a continuous seam between first and second thermoplastic films is provided. The method includes disposing edge portions of first and second thermoplastic films adjacent to one another; disposing a joining process interface (JPI) layer adjacent to a surface of one of the edge portions; and using a heating and compaction device to produce a bonding between at least a portion of the edge portions, and using the heating and compaction device to apply a compaction force against the edge portions of the first and second thermoplastic films. The JPI layer is disposed between the heating and compaction device and the edge portions of the first and second thermoplastic films. At least one of the heating and compaction device and the first and second thermoplastic films are moved relative to the other to produce a continuous seam between the first thermoplastic film and second thermoplastic film.

Method and apparatus for thermoplastic film welding

A modular tooling arrangement includes a base member comprising a planar working surface, a frame circumscribing a first cavity at least partially defined by the planar working surface, and a plurality of plates configured to be received in the first cavity for forming a second cavity of a desired shape and size. The plurality of plates at least partially define the second cavity configured to receive a work piece. The plurality of plates may be replaced with plates of various sizes to vary at least one of the size and shape of the second cavity.
